This paper is concerned with a detection framework under scheduled communication for a binary hypothesis testing problem. A scheduler is designed to smartly select useful sensor measurements for transmission and leave non-useful ones, which results in that only a subset of measurements is sent to the testing agency. To this purpose, a likelihood ratio based scheduler is implemented to decide the transmission...
Along with the improvement of sanitary conditions and changes of life style, people begin to pay attention to the modern concept of health promotion and preventive medicine. Therefore, we built an intelligent environment monitoring feedback system to collect data of physical conditions of employees and air conditions of the working environment, displayed the collected data with a real time interface,...
It is important that balancing the node's energy consumption effectively in wireless sensor network. We propose a novel double cluster-head routing policy based on clustering hierarchy routing. According to balancing the number of neighbor nodes, surplus energy and distance weights, we adopt first and second cluster-head mode. Cluster heads are responsible for data collection and transmission respectively...
Intradialytic hypotension (IDH) is a much common complication during a hemodialysis. The prevalence of IDH is about 10-50%. Elderly people, patients with diabetes, and cardiovascular dialysis patients have the highest rate of incidences. IDH may lead to nausea, vomiting, or anxiety. In some severe cases, there will be accident like shock and death. The purpose of this paper is to integrate the technologies...
The power of nodes in the first layer of a wireless sensor network (WSN) cannot last due to their frequent relay tasks. One possible solution to this disadvantage is to adopt the first order load-balanced algorithm (LBA) to redistribute the loading of the first layer node uniformly. The balanced low-latency convergecast tree (BLLCT) algorithm, a LBA, is generally utilized in route planning in ecological...
Movement control strategy and sensor network deployment are very challenging due to random distribution movement of sensor nodes for mobile sensor networks (MSN), optimization algorithm is becoming a main solution to movement control strategy in MSN. In this paper, an optimizing movement control strategy is proposed for mobile sensor networks. The multilayers mobile sensor network architecture is...
